Moosa Moulana (rah) was once narrating one of his incident at Nizamuddeen

In the winter nights of Nizamuddeen when razai over razai gives very little warmth, one of the elderly man beside him at Markaz was sitting and doing Zikr while almost all were asleep. He was repeating _La ilaha illa Allah_ in a low tune. Moulana could not sleep as he was enjoying listening to the Zikr and could feel the sweetness inside. After a while he came closer to the elderly person and told him that his Zikr was giving sweetness inside his heart. Hearing this the elderly person kissed the forehead of Moulana and said ' *If the listener is experiencing such a sweetness, how sweet is the Zikr for the one who is doing it!* .

Yusuf Ceyloni at Nizamuddeen Markaz says, those days I could not get sleep at night. As some of the brothers would wake up too early for Thahajjud and their cries in Dua become loud out of control and sad for the listeners. _Nowadays also sleep is not getting by those who snore loudly throughout the night_.
